The first observation of about 2000 candidates, with a background contamination below 3%, of the rare decay K± → π±π0e−e+ is reported. The preliminary branching ratio in the full kinematic region is obtained to be: BR(K± → π±π0e−e+)= (4.06±0.17).106 by analyzing the data collected in 2003. A sample...
